Description
AIR-20/M2-MB is a microprocessor-based pressure transmitter by ELEMER with a digital output via the Modbus RTU protocol over an RS-485 interface. It converts absolute, gauge, vacuum, differential and hydrostatic pressure into a digital signal for direct integration into APCS without intermediate converters.
Measurement accuracy is from ±0.1%, protection rating IP65, operating temperature up to -55...+70 °C. The device is equipped with an LED indicator rotatable by ±135° and an external zero-adjustment button, configured via the proprietary ModbusConfig software. Certified to Functional Safety Integrity Level SIL 2.
